*4. migrum, Latr. Mildenhall, Suffolk (D.S.). These 
specimens are somewhat larger and have the dark apex 
of the wing more extended than in 4. femorale, but other- 
wise agree rather closely. Latreille’s description is of 
course inadequate, but the determination seems probably 
correct. Head, fig. 59; hypopygium, figs. 40 and 41. 
Mycomyta, Rond. 
(Sciophila, Winn.). 
This genus seems to me to be in a very unsatisfactory 
state; the following species have been identified by means 
of the male genitalia, but their synonymy in some cases 
is in much doubt. 
*M. affins, Staeg. (= flava, Winn.). Carrow, Cam- 
bridge, Crowborough (F.J.); New Forest (D.S.); Henley- 
on-Thames (H. Scott); Aberfoyle (A.E.J.C.). 
M. incisurata, Zett. This seems to be by far the 
commonest species of the genus here. 
*M. winnertzii, Dz. Common. Probably the S. fasciata 
of the list. 
*M. lucorum, Winn. Felden, Herts. (A.P.); New 
Forest (D.S.). 
*M. wankowickzui, Dz. Common. (New Forest, etc.). 
M. tenuis, Wik. (apicalis, Winn.; radoskowski, Dz.). 
Largs, Logie, Cambridge, C ‘rowborough (F.J.); Nethy 
Bridge (J. W.Y. ); New Forest (D.8.); * Padstow (C.G.L.). 
Walker’s type has lost its abdomen, but as this is one of 
the most distinct species in the genus, I do not think there 
can be any doubt about the determination. 
M. maura, Wik. (lugubris, Winn.). The genitalia of this 
species resemble those of S. penicillata, Dz., rather closely ; 
S. penicillata may perhaps be a synonym or variety. The 
colour, as usual, is very variable; the thorax is usually 
entirely shining black, but some specimens from Aberfoyle 
(A.E.J.C.) have it licht brown with three dark reddish 
brown stripes. 
NEOEMPHERIA, O.-S. 
N. pictipennis, Hal. This is not the same as Empheria 
pictipennis, Winn. All the British specimens I have seen 
have a wing venation resembling that figured by Winnertz 
for N. formosa, but N. pictipennis has similar wing- 
markings in both sexes, while in N. formosa the male has
